WinUI 3 failed to get resources from loaded assemblies when using MEF or Assembly.Load().
microsoft/microsoft-ui-xaml#5536
Describe the bug
Bunch of problems getting loaded assemblies resources when navigating to xaml pages declared on those assemblies.
Steps to reproduce the bug
Steps to reproduce the behavior:
- Create a main "host" winui app
- Create class library project and create a blank page and some resources for that page
- Copy compiled class library, pri and xbf files to host app folder
- Load class library in main app through MEF
Expected behavior
No problem while navigating or creating pages from those loaded assemblies.
Version Info
NuGet package version: [WinUI 3 - Windows App SDK 0.8: 0.8.0]
Updated to Windows App SDK 1.0. Still not getting resources.

Additional context
Similar to microsoft/microsoft-ui-xaml#3888 and microsoft/microsoft-ui-xaml#3657
It is a WinUI module container app which loads different modules through MEF.
MEF composes well and loads all the dlls stored in a "modules" folder inside the main app folder.
Pri files of modules are stored along with dlls files in modules folder.
e.g:
mainapp/modules/module1.dll
mainapp/modules/module1.pri
xbf of modules are stored inside main app folder under its respective Module folder.
e.g.:
mainapp/module1/views/page.xbf
The only way that almost works is in managed only mode and creating instances of that page types through Activator.CreateInstance and assign them to frame.content, but it seems that it (managed) ignores resourcemap not found errors and let you create the page, but without displaying x:uid string resources in the controls, for example. All those string resources are stored in the pri files.
Navigating to a page type through a frame with managed only, throws 'System.AccessViolationException' Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
Different behaviors depending on debug mode (sorry for non english words):
Managed and native with Activator.CreateInstance()
object cp = Activator.CreateInstance(pageType);
NavigationService.Frame.Content = cp;

Disabling winrt:hresult_error does not work for me.
namedresource uri problem? This a section of a module pri file. Those namedresources are not being displayed/parsed by xaml page. Debug does not provides what namedresource is looking for when throwing the error (in native or mixed mode), any idea how to get it?
